The GC Simulations : Quantifying the Dark Side of the Universe in the Planck Cosmology
Tomoaki Ishiyama, Motohiro Enoki, Masakazu A. R. Kobayashi +3
We present the evolution of dark matter halos in six large cosmological N-body simulations, called the GC (New Numerical Galaxy Catalog) simulations on the basis of the LCDM c…
The Impact of Dust in Host Galaxies on Quasar Luminosity Functions
Hikari Shirakata, Takashi Okamoto, Motohiro Enoki +4
We have investigated effects of dust attenuation on quasar luminosity functions using a semi-analytic galaxy formation model combined with a large cosmological N-body simulation. W…
Anti-hierarchical evolution of the Active Galactic Nucleus space density in a hierarchical universe
Motohiro Enoki, Tomoaki Ishiyama, Masakazu A. R. Kobayashi +1
Recent observations show that the space density of luminous active galactic nuclei (AGNs) peaks at higher redshifts than that of faint AGNs. This downsizing trend in the AGN evolut…
Galaxy luminosity function and its cosmological evolution: Testing a new feedback model depending on galaxy-scale dust opacity
Ryu Makiya, Tomonori Totani, Masakazu A. R. Kobayashi +2
We present a new version of a semi-analytic model of cosmological galaxy formation, incorporating a star formation law with a feedback depending on the galaxy-scale mean dust opaci…
